1 Claim.

My invention relates to door frames, particularly to the trim of such frames, and more especially the method of forming the base reinforcement of the trim. The invention is particularly useful in connection with a rolled metal trim although its use is not limited thereto.

An object of the invention is to provide a simple and effective reinforcement for the base of a door frame. Another object is the provision of a reinforcement which will be economical of material and which will require a minimum of time and labor to apply. Other objects will be apparent later.

The invention is illustrated by way of example in the accompanying drawing, in which- Figure 1 is a general view of a doorway constructed in accordance with the invention,

Fig. 2 is a sectional view of the base of the door buck or frame taken on the line II-II of Figure 1, Fig. 3 is a side elevation of the base of the door buck or frame shown in Figures 1 and 2, and

Fig. 4 is a similar elevation as viewed from the front or inner face of the base.

In constructing door casings, or frames, it has been customary to cut out the trim at the base and to insert either a solid casting or a formed-up piece of metal in order to form the plinth block and to reinforce or strengthen the frame. In the present invention the pilaster member is continued to the floor line, and the plinth block is applied thereto without cutting away the trim.

Referring now more particularly to the drawing, there is shown a door way 10 in which a door 11 is hung. The door casing or frame is formed with a rolled metal finish or trim and comprises a lintel 12 beneath which two pilasters 13 extend vertically past a sill 14 to the floor. The bottoms of the pilasters 13'are not cut away but extend to the floor. I A plinth block 15 is applied to each pilaster at this point without cutting awaythe trim,',and as here shown comprises a casting screwed to the face of the trim.

In order to preserve the inner profile of the pilaster member clear to the floor the plinth block need not extend around the inner face of the pilaster, but may be formed in two parts 15a and 151), each part being shaped to conform to the profile of the .trim at one side of the inner face. The plinth block parts 15a and 15b slip over the profile at each side of the pilaster bottom, as illustrated in Figs. 2 and 4. They are fastened to the pilasterfor instance by metal screws 16, 16, and act to reinforce the base of the pilaster.

Thus the plinth block and frame may be fastened together in the shop, and be carried to the work in one piece. Thus the whole may be installed when the building is being erected without the necessity for any cutting, fitting, or fastening at that time.

It will be realized that the invention provides a very simple and effective reinforcement which is economical of material as well as time and labor; it being more efficient to apply the plinth block in the shop and. to avoid cutting and fitting at the point where the building is erected. Further, since a solid plinth block need not be employed where the present invention is used a saving of material results.

It is to be understood that the specific description and illustration here given are merely presented by way of example and that the invention is not limited to the particular form here described.

I claim: I

A door frame comprising a rolled trim having a profile consisting of indentationsand projections, and a plinth block consisting of a casting having its inner surface shaped throughout its height to conform to said indentations and projections,and applied to the face of the trim, the conforming surfaces extending to the floor.
